What is the purpose of foods?

What does naturopathic nutrition focus on?
Use of whole and organic food as medicine
The importance of detoxification and cleansing
Looking at the Constitution of the patient
Finding the cause of disease and not just treating a symptom
Define junk food
Junk food is chemically altered food substances that provide no nutrients and are not able to maintain health and growth
What are some of the constituents of junk food?
Highly processed
Generally contains GM ingredients, artificial colourings, sweeteners, pesticides and other chemical additives
High in calories, sugar, salt, refined carbohydrates and trans fats
Low in fibre and nutrients
Designed to make one over eat due to the chemicals they contain which increase a desire to eat
Often much cheaper
How is junk food unhealthy?
It’s a cellular poison
Hinders the electrical flow between cells
Doesn’t nourish cells tissues
Robs the body of essential nutrients
Destroys cells and impairs body functions
Reduces life expectancy and performance (athletic, cognitive, sexual)
Absorb energy from the body
Accelerates ageing
Addictive - leads to over eating, malnutrition, disease, early death
What are some of the diseases that junk food is associated with?
Atopic conditions e.g. asthma eczema
Hormonal disturbances such as Type II diabetes, PCOS, PMS, infertility, menopause
Skeletal disorders - osteoarthritis, rheumatoid arthritis, osteoporosis
Cardiovascular disease - atherosclerosis (creating endothelial damage) - strokes, angina, etc.
Neurological issues - migraines, Parkinson’s, Alzheimer’s
Contribution to cancer pathogenesis (carcinogenicity)
What are natural food sources?
Animals - e.g. meat, poultry, game, fish, seafood and animal byproducts (eggs and dairy)
Plants - e.g. vegetables, fruit, culinary herbs and spices, grains, seeds (sprouts), nuts, legumes
What food should you avoid?
Processing package foods
Ready meals
Junk foods
Sweets
Juices and fizzy drinks
What is the difference between grain fed meat and grass fed meat?
Grain fed meat has a high omega 6 (inflammatory) to Omega3 (anti-inflammatory) ratio - 20:1.
It is high in inflammatory fatty acid - arachidonic acid
Grass fed and wild meat has a ratio of Omega 6 to 3 of 2:1. It is 10 times less inflammatory
It has higher conjugated linoleic acid (CLA), which regulates heart health, bodyweight and blood sugar levels
What is the difference between organic and non-organic meat?
Organic has higher vitamin, mineral and amino acid profile (including beta-carotene and vitamin E). It has higher animal welfare standards.
Non-organic may contain chemicals and xenoestrogens
What are red meats?
Pork
Beef
Lamb
What are the benefits of red meat?
Complete protein (contains all nine essential amino acids)
Polyunsaturated fats
Iron
Zinc
B vitamins
Phosphorus
Selenium
What are the negatives of red meat?
High cholesterol and saturated fats
No fibre
High animal protein intake requires more energy to be digested, placing more burden on the digestive system whilst the high formation of protein metabolite stresses the kidneys
Pro inflammatory - heart disease, diabetes, cancer, arthritis, asthma, osteoporosis, obesity, Alzheimer’s, impotence
Acid forming (due to high sulphur content = sulphuric acid)
What is poultry?
Chicken
Turkey
Goose
Duck
Pheasant
Cartridge
Pigeon
Poussin
Ostrich
Emu
What are the benefits of poultry?
Complete protein
Vitamin B1, 2, 3, 5, 6, 12, E
Zinc, Iron, magnesium
Less saturated fat (but also less B12 than red meat)
What are the negatives of poultry?
Food poisoning risk (especially campolybacter and salmonella)
Often intensely farmed, poor welfare standards
- always opt for organic, pasture reared, heritage breeds or wild poultry products
What are the benefits of eggs?
A complete protein (more than half the protein is found in white)
Vitamin A, D, B6, B12
Selenium, Zinc, Iron and copper
Choline
Brain health (essential nutrients including choline)
Immune system (vitamin A, B12, selenium)
Pregnancy health (folate and choline for embryo development)
Eye health (vitamin A and antioxidants)
Cardiovascular health (generally raise HDL cholesterol, choline helps to break down the amino acid homocysteine
What are the negatives of eggs?
High in arachidonic acid - pro inflammatory
What is choline?
A vitamin like substance, also produced in small amounts by the body
Name some fish
Cod
Tuna
Seabass
Mackeral
Sardine
Trout
Salmon
Herring
Benefits of fish
Complete protein
Omega 3
Vitamin D, B2
Calcium, phosphorus, iron, zinc, iodine, magnesium, potassium
